One way video, any browser, webrtc2sip and Asterisk to softphone

[GoogleCodeExporter]

The problem occurs when I make or receive a call from Firefox or Chrome, via 
webrtc2sip and asterisk to a softphone (Ekiga). I've attached the sipml5 log 
file.

I think I'm getting audio in both directions (the mic is faulty on one 
machine), but video only in one direction. Video is sent from the web browser 
to the softphone, but doesn't get back to the web browser. There are messages 
appearing in the webrtc2sip debug:

*[DOUBANGO INFO]: Incoming SIP INFO(picture_fast_update)
*[DOUBANGO INFO]: ***IDR request tooo close(2 ms)...ignoring****

and 

**[DOUBANGO WARN]: function: "tdav_codec_h263_decode()"
file: "src/codecs/h263/tdav_codec_h263.c"
line: "440"
MSG: Buffer overflow

Also, before video starts I get thousands of 

*[DOUBANGO INFO]: Sending DNS query to "192.168.1.250"
*[DOUBANGO INFO]: Sending DNS query to "192.168.1.250"
*[DOUBANGO INFO]: Sending DNS query to "192.168.1.250"
*[DOUBANGO INFO]: Sending DNS query to "192.168.1.250"

appearing in the webrtc2sip log.

The asterisk config allows g722 and h263 only.

It's probably something that isn't configured correctly, or a mistake in my 
sipml5 code, but I'd be grateful for some help solving this problem.

thanks,

Charles.

I've tried using h264 instead of h263 and get the same problem:
